Claims. 1

The present invention relates to improvements in a hair trimming andshaving attachment for a comb and has for an object the provision of adevice of this kind which is adapted to be quickly mounted upon andremoved from a hair comb.

Another object of the present invention is to provide an improved razorattachment which is especially adapted to be demountably attached to thetype of comb disclosed in my prior U. S. Patent No. 2,481,403, grantedSeptember 6, 1949, for a Barber Comb.

A further object of the present invention is to provide an improveddevice of this character which is capable of being adjusted so that thesize of the cuts may be selectively varied.

A still further object of the present invention is the provision of animproved razor attachment for combs with which the hair of a person maybe cut, trimmed, thinned and shaved and also combed at the same time.

Still another object of the present invention is the provision of adevice of this type which can be efficiently used not only by skilledpersons, such as barbers, and operators of beauty parlors, but also byunskilled persons and even by children.

The present invention aims to provide an improved razor attachment forcombs which comprises relatively few parts and is economical tomanufacture.

In one of its broadest aspects the present invenitioncontemplates theprovision of an improved :razor attachment for a hair comb comprising amounting member for attachment to a hair comb, a clamping plateassociated with said member, :and means carried by said plate andadapted to clamp a razor blade against the teeth of the comb when therazor blade is positioned between said plate and the teeth of the comb.

More specifically the present invention contemplates the provision of animproved razor attachment for a hair comb comprising a mounting memberof substantially inverted U-shape and having a bridge portion, a pair ofspaced apart legs depending from the bridge portion, a flange extendingupwardly, rearwardly and downwardly from the bridge portion for engagingover the back of the comb and a hook extending rearwardly and upwardlyfrom the lower end of each leg for engaging the free end portions of theteeth of the comb, a guide portion member on each leg of the mountingmember and each comprising a strip attached to its leg and a secondstrip verlying a portion of the space between said legs, a clampingplate vertically adjustably mounted between said guide members andhaving a screw threaded openingtherein, a boss ex tending from theforward face of said plate and having a screw threaded bore in alignmentwith the opening in theplate, lugs projecting from the rear face of saidplate to be received by the slots in a razor blade when the razor bladeis placed between the plate and the comb, a screw received by theopening in the plate and the bore in the boss and adapted to beprojected beyond the rear face of said plate to engage the'razor bladeand to force the razor blade against the teeth of the comb and to forcethe forward faces of the opposite marginal end portionsof said plateagainst said second strips of the guide members, whereby the clampingplate and the razor blade will be firmly held in place, the lower endportion of each of saidsecond strips being curved downwardly andrearwardly to be disposed in the path of the downward movement of saidplate.

With the foregoing and other objects in view, the invention will behereinafter more fully described and more particularly pointed out inthe appended claims.

In the drawings, in which the same parts are denoted by the samereference numerals throughout the several views,

Figure 1 is a front perspective view of the improved device constructedin accordance with the present invention and illustrated as applied to ahair comb,-.

Figure 2 is a rear proved device,

Figure 3 is a rear ing plate,

Figure 4 is a vertical sectional view taken through the center of thedevice shown in Fig ure 1,

Figure 5 is a sectional 5-5 of Figure 4 and the arrows.

Referring more particularly to the drawings, l0 generally indicates theimproved razor attachment which may be applied to the conventional typeof hair comb but in the present illustration is shown as mounted on acomb generally indicated as H of the construction disclosed in my priorU. S. Patent No. 2,481,403 mentioned above. Only the large end portionof the comb is shown, but as is well known in hair combs of this typethe back or body [2 of thecomb ll progressively increases in width fromthe smaller end of the comb towards the large end 13 thereof. From thelower edge of the back I2, a group of spaced perspective view of theimperspective view of the clampview taken on the line looking in thedirection of 3 apart teeth 14 depend having tapering side walls l5 andE6.

The back or body portion of the comb is formed with a portion I!extending beyond the edge of the body to which the teeth are afiixed andlaterally outwardly from the teeth. The inner surface or portion l8 ofthi extending portion I? is inclined at a relatively sharp angle towardthe center of thetoothed edge of the body, thereby forming a knife-likeledge l9 extending continuously along the entire length of the teeth 14.As clearly shown in Figure 4 of the draw'-' ings, the ledge or marginaledge IQ of the extended portion I! defines a, recess or space. 29between the inclined surface [8 and the adjacent surfaces 2| of theteeth.

The improved razor attachment l9 comprises a mounting member 22 andaclamping plate 23 which may be made of metal, plastic orany othersuitable material. be of substantially inverted U-shape and ha a bridgeportion 24 and a pair of spaced apart legs 25 depending from theopposite end portions of the bridge portion 24 to provide a space 25:!therebetween. flange 26 extends from the upper edge of the bridgeportion upwardly, rearwardly and downwardly for engaging over the back12 of the comb. A hook 21 extends from the lower end of each of the legs25 rearwardly and upwardly for engaging the free end portions of theteeth l4 of the comb.

A guide member 28 is attached to each of the legs 25 and each guidemember comprises a pair of strips 29 and 30 arranged in steppedformation with the strip 23 attached to. the forward face of its leg inany suitable manner and a portion of the strip 30- overlying theadjacent outer side area of the space 25a.. The strips of each guidemember 28 may be. formedv integral or they may be secured. together inany appropriate manner and the. guide. members may be formed of steel,plastic or other suitable material.

The clamping plate 23 which. is more clearly shown in Figure 3 of thedrawings may be of substantially oblong shape and. has a substantiallycentrally disposed screw threaded opening 3| therethrough. A boss 32extends from the forward face of the plate 23 and has a screw threadedbore 33 extending thcrethrough in alignment with the opening 3| of theplate. A

pair of spaced apart lugs 34 are positioned. on

each side of the opening 3t and extend from the rear face of the plate23'. The lugs 34 are of substantially the same size and shape as theslots 35 of a conventional type of razor blade 36 by which they areadapted to be received. A screw 31 is received by the bore 33 of theboss 32 and is adapted to be threaded into the opening 31 of the plate23 to have its inner end portion to project beyond, the; rear face ofthe plate. The diameter of the screw 31' is larger than that of the hole38 in the razor blade 35 so that when the razor blade is mounted on thelugs 34 of the plate 23 the inner end of the screw 3'! will engage theareas of the razor blade which surround the hole 38 of the blade. Thelower edge of the plate 23 may be beveled as at 39 and the lower endportion of each of the strips 33 of the guide member 28 may' be curved.downwardly and rearwardly as at 40' to engage the beveled lower edge 39of the plate 23 when. it is in its lowermost position.

In the use of the device, the mounting member 22 is slid upon the comb Hfrom the small end The mounting member may A substantiallysemi-circularthereof so that the flange 25 of the member 22 will engageover the back l2 of the comb and the hook 2'! will engage over the lowerportions of the teeth [4. The member 22 is moved along the back l2 ofthe comb towards the large end [3 of the comb until the flange 26 has atight fit with the back 12. The razor blade 36 will then be placed uponthe rear face of the clamping plate 23' with the lugs 34 disposed in theslots 35 of the razor blade. The plate and the razor blade will then beinserted into the upper ends of the guide members 28 between the strips36 and the teeth M of the comb with the razor blade next to the teethl4. The user will adjust the plate and the razor blade to the properheight on the mounting member 22 dependent upon the depth of the cut ofthe hair desired. For the purpose of assuring the proper adjustment, oneof the strips 38 may be provided with a vertical column or scale ofindicia 4|, such as l, 2, 3 and 4, and the front face of the plate 23may have an index 42,. such. as. an arrow, formed thereon forassociation with the indicia 4! to indicate various cutting positions ofthe razor blade.

When the proper cutting position of the plate and blade has beenobtained, they may be locked in this position by turning the screw 3?while holding the late and the blade until the blade 36 is urged intoengagement with the teeth l4 of the comb. Further turning of the screw31 in the same direction will cause the plate 23 to back up on the.screw against the strips 30 as illustrated in Figure. 4 of the drawings.In this position of the parts, the blade will be frictionally heldagainst the teeth. 14- of the comb against movement and the plate willbe held frictionally against the strips 30 against movement. The lugs 34are of sufiicient depth that they cannot escape from the slots 35 of theblade 36 when the plate 23 is backed up away from the blade but the lugs34 will be received in the spaced between adjacent teeth 14 of the combto engage therewith to augment the clamping action of the plate. andscrew in preventing rotation of the razor blade and. the plate.

The device is now ready to use for cutting the hair and the user willgrasp. the small end portion of the comb H. in hi hand. and pass thecomb and razor attachment downwardly with the lower edge of the bladecontacting the hair of the person having his hair cut. The extendingportionj H of the, comb will. be disposed to wards the hair to be cut.Afterv the hair has been cut, the razor attachment may be removed byloosening the screw 3'! until the lugsv 34 can be withdrawn from betweenthe teeth M of the comb and the member 22 will then he slid towards thesmall end of the comb and removed therefrom. The comb may then be usedto comb and set the hair.

If a woman desires toprepare her own hair for a home permanent shewillinvert the comb H and comb asection of. her hair about three inchessquare. The user will hold the tip of each swatch or portion of hairwhich she desires to thin and shape. The comb will be inverted and therazor blade passed down on the swatch of hair from the top and shape andthin under and over. When the thinning; shaping and cutting operationhave been finished, the user. will remove the razor attachment and usethe comb to finish the settin of the hair.

When the plate and blade is adjusted so that the arrow 42 points to thel; of the scale 4|, the

device is set for shaving the backofthe neck, the hair on the legs orthe hair under the arms. When the plate and blade are adjusted so'thatthe arrow points to the 2, 3 or 4 of the scale, correspondingly largercuts will be made. By inverting the comb, the comb may be used forcombing down the hair to prepare it for another cut and at the same timecleaning the section of hair that has already been cut. The smaller endportion of the comb provides a comfortable grip, affords greatercleanliness and effects a saving of time.

It will be noted that all kinds of double edge razor blades can be usedon the attachment.
